Understanding NAD+ for Better Aging: Insights from Dr. Greg Kelly | Ep #263

About this video

Niddam interviews naturopathic physician Dr. Greg Kelly for a deep dive on NAD biology, its vitamin B3 origins, and why levels and cellular resilience may decline with age and stress. Kelly explains precursor supplements, timing considerations, and laboratory testing of NAD status, and discusses why, in his account, direct NAD infusions face delivery and balance questions despite reported benefits for some users. He discloses his role developing a commercial NAD-support formula and cites company testing in its favor. The episode closes with both speakers ranking sleep, movement, nutrition, and stress management as the foundational investments that supplements can only round out.

Key takeaways

• Understanding a molecule’s whole metabolite family gives more context than tracking one marker
• Timing and baseline testing are presented as part of judging whether a supplement is working
• Large molecules face a cell-entry problem that delivery claims need to answer
• A guest’s commercial role in a product discussed is relevant context for weighing their evidence
• Supplements are framed as portfolio additions, never substitutes for sleep, movement, and diet
